Final answer:
Glucose and glucose can form maltose through dehydration synthesis, while cellulose can be broken down into glucose through hydrolysis. Sucrose can also be formed through a condensation reaction, and glucose and galactose combine to form lactose.
Step-by-step explanation:
In biology, glucose and glucose can be combined through a dehydration synthesis reaction, which forms maltose and a water molecule. Conversely, cellulose can be broken down into glucose and water through a hydrolysis reaction. Additionally, other reactions involving glucose include the formation of sucrose through condensation reaction and the formation of lactose through the combination of glucose and galactose.
